Quick fix for a Norcold...

We were at the Rainbow CG in the White Mountains of eastern Arizona last week. Most of our trips are off of the grid so the gas side of the refrigeration equation usually gets a workout. Our 7 year old Norcold frig has always performed flawlessly but for the first time, I had a problem.

After setting up our site with the frig set to Auto which triggers the propane {absent AC power} everything was fine for a few hours and then I began to get the flashing yellow light indicating a problem {Check system}. I reset the system and sure enough, in a few hours, the failure alert repeated.

I fired up the generator and the frig ran fine on AC power... hmmm :h

I tried lowering the thermostat setting as well as shutting everything down and restarting but the problem persisted. We had plenty of propane and then it hit me... at 9,000'+ perhaps I had sucked a little thin air into the propane line. I lit a burner on the stove, it was time for our morning pot of coffee anyway, and reset the frig one last time.

" Voila!" we were back in business and the frig ran perfectly for the next 3 days. I guess if there was air in the line lighting the stove burner purged/pulled it through and solved the problem. Just thought I'd share something that worked. You're welcome.

  • Just trying to be helpful... so if lighting a burner and getting LP flowing through the system is no cure why does it now work? Nothing else has changed. Just thought {hoped} this simple fix might help someone else someday... What was I thinking? :h

    Perhaps one of our resident citics can explain what was wrong and why it now works.
    For the record the water heater and furnace both worked just fine the entire trip.

    :S
  • You have a burner that is simply carboned up. Take out the burner tip and wire brush the carbon off and will be fine.You will see a loop in the line that lets you pull the burner out. It's easy.

    Also very often the chimney gets cob webs and slows down so all you need to do is blow air up the chimney with compressed air. Sometimes you have to remove the vent cover on the roof and clean that so it has good flow again.
  • Don't you have to adjust the A/F mixture when you are at a higher altitude? That's moving that sliding bar thing on the gas tube to allow for more 'air'..

    Probably have to do the same thing for the water heater too running on gas..

    I know my TT has that sliding thing to adjust the flame and it's a pretty old TT...

    Good luck!

  • We had an issue with a gas water heater at over 7500 feet elevation once. I fiddled around, cleaned the heater jet, pondered, drank beer---- the next morning, the thing worked just fine. Later that day, I discovered that the propane tank had changed over sometime in the last 24 hours. HMMMMM...........
    Whatever happened? No clue.

    OK


    I keep hearing that old "Air in the line" thing... And shaking my head for the exact reason you stated..
